Eleventh Air Force

Projectile Motion Worksheet A ball rolls off a desk at a speed of 3.0 m/s and lands 0.40 seconds later. How far from the base of the desk does the ball land? How high is the desk? What is the speed and angle of impact? A slingshot is used to launch a stone horizontally from the top of a 20.0 meter cliff. The stone lands 36.0 meters away. At what speed was the stone launched? What is the speed and angle of impact? A ball rolls with a speed of 2.0 m/s across a level table that is 1.0 m…

“We can apply Newton’s first law by minimizing the forces that resist motion. The way we will do this is to make the nose cone as smooth and pointy as possible. If the nose cone is too flat on the end, it will not cut through the air very well. The rocket must cut through the air swiftly, this means that resistance will be at its minimum during flight. We would like the least resistance because that means the rocket will glide and not stall mid-air because that will affect flight time.” It’s…

implies that the two bodies of masses M and m, and the radius vectors r ⃗_M and r ⃗_m , respectively, would exert the following forces of mutual gravitational attraction: Figure 1.2. A two-body interaction coordinate system. Two masses M and m at the radius vectors rM and rm , respectively. Force on m: F ⃗_m = -m( r) ̈_(m )= -- GMm/r^2 r ⃗/r (1.5a) Force…

pendulum is twice bigger than the period of the lever oscillation. Piston of the pump has reverse effect on the lever and damps its oscillation. Damping of the lever motion causes damping of the pendulum, but the work of the force damping the pendulum is less than the work of the forces which damp the lever. Equilibrium position of the lever is horizontal, and the equilibrium position of the pendulum is vertical. Oscillation of the lever and the pendulum take place in the same plane, vertical in…

affect the speed of sound would include the density of the item through which the sound is traveling. Continuing on with that concept, when sound is traveling through the air at a certain speed, factors may include the temperature, dampness and humidity of the air, and the density of the air as well. The speed of sound through the air is measured to be to be 343 meters per second. The speed of sound…

(acceleration) is proportional to the net force and inversely proportional to the mass. Background Theory: Sir Isaac Newton presented his three laws of motion in the Principia Mathematica Philosophiae Naturalis in 1687. The second law, ΣF = ma, states that changes in force will cause an object to accelearate and with this equation, one can figure out how much. It can be rewritten into a = ΣF / m, and thus, it can be seen that acceleration is proportional to net force and inversely proportional…

Dynamic Traction Control (DTC) is a sub-function of the Dynamic Stability Control (DSC) system that can be turned on and off. DTC has two major roles: to regulate traction and to enable sports-style driving while providing active stability control. When the drive wheels start losing traction the DSC automatically begins stabilisation measures. The Dynamic Stability Control system curbs the engine output and stops slip on the wheels. In exceptional situations, however, a small amount of wheel…

Equilibrioception is the sense of balance and a process that takes place within the body. Balance is maintained by the human body during both normal posture and movements. Thus, equilibrioception is a continuous process that takes place unconsciously in the body for the most part. This procedure requires the input of information from the vestibular, visual and proprioceptive systems. Motor output is relayed through two separate pathways in response to the integration of the information. Thus,…

acceleration and there must be an external force causing centripetal acceleration. As shown in the diagram, the only thing in contact with the car is the road, which is between the tyres of the vehicle and the surface of the road. Therefore, we can know that the frictional force exerted between the tyres and the road directed to the centre of the arc of which the car is travelling, is the causative force for centripetal acceleration. F= Frictional force between tyres and road F=ma^c F=(mv^2)/r…
